Trolex Ltd

For over 40 years, Trolex has specialised in the design and manufacture of sensors for safety critical industries.  Through an ongoing research programme, the company has developed a comprehensive range of programmable controllers, trip amplifiers as well as a selection of sensors for temperature, flow, level, pressure, gas, flame and vibration.

Trolex has recently introduced an 8-channel programmable sensors controller capable of handling virtually any standard sensor input and each channel can be individually programmed on-site to meet the specific needs of the customer. The unit meets a wide range of safety guidelines that allow it to be used as the control unit for any combination of transducers or transmitters.

 

The 8-way controller is available from Proviso Systems, who have also undertaken the task of writing dedicated software to complement its capabilities. The Windows based software will provide alarm icons, current running levels and trend displays for up to 32 sensor controllers.
